paranormal electronics

We hasten to reassure our readers, lest our use of the word `paranormal` should conjure up visions of unspeak- 11ble hags dancing around cauldrons with uneatable contents, or of bats capering around the crumbling crenellations of crepuscular ·carpathian castles. We are not attempting to delve into the occult, but on the other hand the articles that will be presented in this and the next issue are not a series of `trick or treat` gimmicks for Hallowe`en. What we are attempting to do is to take a look at some phenomena that are on the fringes of 9ur normal experience, such as the physiological effects of electric and magnetic fields, biofeedback, sub- liminal perception and precognition, Kirlian photography and so on; areas bf investigation in which electronic circuits have many applications.
